'These cries for help are not about minor conflicts that could be resolved by greater generosity on the part of the one praying or by the exercise of love of neighbor. Rather those who pray these psalms are crying out about the injustice they suffer and are protesting about the arrogance of the violent. They are impelled by the contradiction posed by the mystery of evil and the presence of evil people in a world supposedly in God's care. This is no a trivial or selfish complaint: they are protesting not just because they are being hurt, but because God's justice, goodness, and power are at stake. These are not mere grievances about their own suffering, rather they are protests about the challenge that real wickedness poses for believers in an omnipotent God of love. The passion that drives these laments arises from a belief in God's justice that is called in question by unrestrained evil.'
Gordon Wenham, The Psalter Reclaimed, p.139.
